The first instar: Caterpillar larvae vary in size and are capable of being between 1.5-2.0mm in length. [3] At this stage a hatchling lacks its characteristic coloring and instead tends to be a translucent lime green with green or black tentacles and green protuberances along the skirt which lack the long spiny thorns that are seen in older ...
The larvae are black with orange spots arranged in lines down the whole body. Their head's prothoracic shield, and the anal plate, are one color, either green or orange with small black dots. [3] A tail-like spine protruding from the back of the body is a typical for sphingid moth caterpillars, known as “hornworms”. [2]
Sometimes the shed exoskeleton is eaten. Newly hatched, this caterpillar constantly munches on the leaves of walnut, hickory, sweetgum, and paper birch trees. Each instar is green, though the first two instars do have some variation in which some larvae will have black underlying splotches on their dorsal side. The final instar grows to ...
This instar possesses a similarly bicolored prothoracic shield and reduced dorsal setae. There are dense black dots found laterally along the length of the caterpillar's body during this stage. This instar is bright green in color, which mimics the color of the host plant. This stage lasts for an average period of about 11 days. [2]
The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings. The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and ...
The eggs hatch after 1.5–2 days, and the caterpillars grow through five instars over 11–13 days, to reach a final length of 40 millimetres (1.6 in). The caterpillars are green and smooth, with a rounded head, and develops a series of black dots and a white lateral line on top of the plain green ground colour.
— Larva greenish, with yellow and black dorsal markings , white lateral stripes and large black dots, head green; in autumn on Biscutella species; it is a so-called cannibal-caterpillar. Pupa light brown, also green, very strongly incurved (Spuler). [3]
Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, [4] is a butterfly found throughout much of North America. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes.
